How do you keep a chat input fixed to the bottom in responsive Adalo?
Enable Sticky while scrolling on the chat composer, verify its parent hierarchy, and test the pinned layout at every supported screen size.
Short answer
Select the text input or the group containing the whole chat composer, place it at the bottom of the screen, open Layout, and enable Sticky while scrolling.
The intended outcome
The chat composer stays in its chosen bottom position while the messages or other page content scroll behind it.
Place the complete chat composer at the bottom, apply Sticky while scrolling to its intentional parent group, and verify the result with enough messages to scroll at every supported breakpoint.
Requirements
- A responsive Adalo app with access to the Layout tab
- A text input and send control placed together as one chat composer
- Enough page content to make the screen scroll during testing
Step by step
Step 1: Group the chat composer
Place the text input, send button, and their background inside one intentional group or rectangle so the controls move together. Confirm their parent and child order in the component tree.
Step 2: Place the group at the bottom
Move the completed composer to its intended bottom position at the mobile breakpoint before enabling sticky behavior.
Step 3: Enable Sticky while scrolling
Select the composer group, open the Layout tab, and turn on Sticky while scrolling. Adalo keeps the selected component or group in the same screen position as the page scrolls.
Step 4: Check every supported breakpoint
Open the mobile, tablet, and desktop layouts you support. Adjust shared or custom positioning only where the composer needs a different width or bottom location.
Step 5: Test with real scrolling content
Preview the screen with enough messages to scroll, then focus the input, scroll the message area, and send a test message while watching the composer position.
The underlying logic
Sticky while scrolling pins the selected component or group to its current on-screen position while other screen content scrolls.
Grouping the input, button, and background makes the entire composer follow one sticky setting instead of allowing its controls to move independently.
What still needs checking?
- This is a forum-native Answer with no original Adalocado video. Current Adalo documentation confirms the responsive Layout control and parent-child grouping behavior.
Common failure modes
Confirm Sticky while scrolling is enabled on the composer group itself, not only on a child input, and inspect the component tree for an unintended parent container.
Add enough bottom space to the scrolling content for the full composer height, then test the final message at each supported breakpoint.
Put the input, send button, and background in the same intentional group and apply the sticky setting to that group.

Current limitations
- The Layout tab and Sticky while scrolling control apply to responsive builder apps, not Legacy Builder screens.
- A sticky composer can overlap scrolling content unless the screen reserves enough bottom space for its height.
- The forum source confirms the setting but does not include a follow-up reproduction from the original author.
