Is there a way to create component that always top position in personal app like a button in retool?
You can add app specific custom CSS to any app using the "..." menu in the top right corner under "Scripts and Styles"
Unfortunately though it looks like with our new layout, position: sticky, which would be the property you would want for this here is not currently supported.
We are working on building navbars and potentially sticky containers soon, so you could place a table inside of a navbar/header and have it stay at the top.
Hope this helps, let me know if you have any questions!
