How to Make Clean Switchable Tabs in Unreal Engine 5.7 Widget Switcher Guide

What You Will Build

• A reusable tab window widget
• A blurred glass-style background panel with rounded corners
• A horizontal tab bar with multiple buttons
• A Widget Switcher with separate content pages
• Blueprint logic that switches pages instantly on button click
• A UI element you can reuse for settings, tutorials, save and load screens, level selection, and inventory pages

Why Use Widget Switcher in Unreal Engine UI

The Widget Switcher is one of the cleanest ways to manage multi-page UI in UMG. Instead of manually showing and hiding several widgets, or stacking messy visibility logic all over the place, the switcher keeps one active child visible at a time and lets you swap pages by index.

That makes your interface easier to maintain, easier to expand, and much less annoying to debug later.

Brutal truth: a lot of bad UI systems in Unreal happen because people skip structure and start patching visibility toggles everywhere. The Widget Switcher exists so you do not have to do that nonsense.

Step 1: Create the Base Widget and Set the Canvas Size

Start with a new empty Widget Blueprint. This widget will later be added into your main UI, so it acts as a reusable tab component rather than the whole HUD.

In the Designer, drag a Canvas Panel into the hierarchy.

Then change the preview size from Fill to Custom and set the dimensions to:

• Width: 600
• Height: 500

This gives you a controlled working area and makes layout easier to manage.

Step 2: Add a Background Blur for the Main Panel

Search the Palette for Background Blur and place it inside the root canvas.

Set its anchors to the full-stretch preset, the one that fills the entire available area. Then set all offsets to:

• Left: 0
• Top: 0
• Right: 0
• Bottom: 0

Keep the alignment values at 0 and set the Z Order to:

-1

This ensures the blur stays behind the rest of the UI elements.

Increase the Blur Strength to:

10

That is a practical value for a soft glass-style background without making it overly muddy.

Step 3: Create Rounded Corners on the Blur Panel

One useful detail in this setup is giving the blur panel rounded corners. In the Background Blur details, expand the advanced appearance settings and set all four corner radius values to:

50

This changes the panel from a plain sharp rectangle into a softer, cleaner interface block.

It is a small detail, but small details are what separate a rough prototype from a UI that actually looks thought through.

Step 4: Build the Tab Bar with a Horizontal Box

Search for a Horizontal Box in the Palette and drag it into the canvas. This will become the top navigation bar for the tabs.

Set its anchor to the top preset and adjust the slot height to around:

60

That gives enough room for the tab buttons while keeping the bar compact.

The horizontal box is the right layout choice here because it makes multiple buttons line up cleanly across the top and lets them expand evenly.

Step 5: Add the First Tab Button

Drag a Button into the Horizontal Box. Then, in the Horizontal Box slot settings for that button, change the size rule from Auto to:

Fill

This makes the button expand and share space evenly in the tab bar.

Add a Text widget inside the button and change its content to:

Tab One

Set the font size to something readable, such as:

28

and choose a text color that works with your panel style. In the example, black is used.

Then select the button itself and enable:

Is Variable

Rename it to something clear, such as:

TabButton

Add a small amount of padding in the Horizontal Box slot, around:

1

to create a little visual space between buttons.

Step 6: Duplicate the Tab Buttons

With the first button ready, duplicate it twice using:

Ctrl + D

This gives you three buttons total. Update the text labels so they read:

• Tab One
• Tab Two
• Tab Three

Make sure all duplicated buttons still have Is Variable enabled. That is required because you need to bind click events for all of them later.

Step 7: Add the Widget Switcher

Now it is time to add the actual multi-page content system.

Search for Widget Switcher in the Palette and drag it into the root canvas panel.

Set its anchors to the full-stretch preset, then adjust the offsets to:

• Left: 0
• Top: 60
• Right: 0
• Bottom: 0

That places the switcher directly below the tab bar so the top 60 units remain reserved for the buttons.

In the switcher settings, you will see:

Active Widget Index

This is the property that decides which page is currently visible. Later, each tab button will set this value through Blueprint logic.

Step 8: Create the First Tab Content Page

Drag a Canvas Panel into the Widget Switcher. Set its horizontal and vertical alignment to Fill so it occupies the whole switcher area.

Then add a Text widget into that canvas and change the content to:

Tab One Content

Enable Size to Content, then set the anchors to the center preset. Set:

• Position X: 0
• Position Y: 0
• Alignment X: 0.5
• Alignment Y: 0.5

This keeps the text perfectly centered inside the page.

Step 9: Duplicate the Content Pages

Duplicate the first content canvas twice so the Widget Switcher contains three separate child pages.

Update the text in each one to:

• Tab One Content
• Tab Two Content
• Tab Three Content

One useful thing about the Widget Switcher is that selecting a child page in the hierarchy automatically shows that page in the Designer preview, so it is easy to visualize what each tab currently contains.

Step 10: Make the Widget Switcher a Variable

Before creating the Blueprint logic, select the Widget Switcher and enable:

Is Variable

This is required so you can reference it inside the Event Graph.

Step 11: Add Blueprint Logic for Tab One

Select the first tab button, scroll down to the Events section, and click the plus icon next to:

On Clicked

This creates an event in the widget’s Event Graph.

Drag the Widget Switcher variable into the graph. From it, call:

Set Active Widget Index

Set the index value to:

0

Then connect the button’s On Clicked execution pin into that function.

That means clicking the first tab activates the first content page.

Step 12: Add Logic for Tab Two and Tab Three

Repeat the same process for the other two buttons.

For the second tab button:

• Add its On Clicked event
• Call Set Active Widget Index
• Set the index to 1

For the third tab button:

• Add its On Clicked event
• Call Set Active Widget Index
• Set the index to 2

That is the complete switching logic. No weird visibility juggling. No extra complexity. Just three buttons setting three indices on the switcher.

How the Widget Switcher Logic Works

The full system is simple:

1. The tab bar contains three buttons
2. The Widget Switcher contains three content pages
3. Each button click sets the active widget index to the matching page number
4. The switcher shows only that selected page

That is why this approach scales well. Add more buttons, add more child pages, assign the matching indices, and the same structure keeps working.

Step 13: Add the Tab Widget into Your Main UI

For the final step, open your main widget blueprint.

In the Palette, search for the tab widget you just created, such as:

WBP_WidgetSwitcherTab

Drag it into the designer and set its size to match the dimensions used earlier:

• 600 x 500

Place it wherever you want it to appear on screen, then compile, save, and run the game.

Clicking each tab should now switch the content instantly.

Why This Tab System Is Reusable

This setup is not just for one menu. That is the whole point.

Once built, the same Widget Switcher pattern can be reused for:

• Settings menus
• Save and load pages
• Tutorial windows
• Inventory categories
• Level selection screens
• Profile or stats panels
• Any interface that needs multiple switchable views

That is why the Widget Switcher is one of the most practical UMG tools in Unreal Engine. It solves a common problem without turning the Blueprint logic into a swamp.

Common Mistakes to Avoid

• Forgetting to enable Is Variable on the buttons or Widget Switcher
• Not matching button index values to the correct content page order
• Using visibility toggles everywhere instead of a switcher
• Forgetting to offset the Widget Switcher below the tab bar
• Building the layout without a proper root canvas structure
• Ignoring Z Order and accidentally placing the blur above the content

Conclusion

In this Unreal Engine 5.7 Widget Switcher tutorial, you built a clean reusable tab system by creating a glass-style background panel, a horizontal tab bar, multiple content pages, and simple Blueprint logic that switches pages with Set Active Widget Index.

This is exactly the kind of UI structure that scales well and stays maintainable as your project grows.

Frequently Asked Questions

What is a Widget Switcher in Unreal Engine?

A Widget Switcher is a UMG container that holds multiple child widgets but displays only one at a time based on the active widget index.

Why use Widget Switcher for tabs in UE5?

Because it gives you a clean way to switch between multiple pages without manually showing and hiding several widgets with messy visibility logic.

How do I switch tabs with Blueprint logic in Unreal Engine?

Bind each tab button’s On Clicked event to the Widget Switcher and call Set Active Widget Index with the correct page index.

Can I use this system for settings menus and inventory pages?

Yes. This exact structure works well for settings menus, save and load windows, tutorials, inventory layouts, and any UI that needs multiple switchable pages.

Why is my tab button click not switching the content?

Usually because the button or Widget Switcher is not marked as a variable, the click event is not bound correctly, or the active index does not match the correct child page order.

Why put the Widget Switcher below the tab bar with a top offset?

Because the tab bar needs its own reserved space at the top of the layout. Offsetting the switcher keeps the content area from overlapping the buttons.
