How to implement or use an accordion panel in MATLAB App Designer?

Hey, I like to create an accordion panel in MATLAB App Designer . Specifically, I want a component similar to a tree structure but with collapsible panels instead of nodes. Each panel should expand or collapse when clicked, and it should contain various UI components (buttons, sliders, etc.). Does MATLAB have a built-in feature for accordion panels? If not, are there any recommended third-party components or custom implementations I could use? Sample code or guidance would be appreciated.(for the example the like the picture I uploaded)

Hi Lidor,

It looks like the picture is not attached. I assume that you are trying to create a collapsible panel in MATLAB App Designer.

MATLAB does not have a built-in feature for collapsible panels. However, this File Exchange submission by a MathWorks staff member supports collapsible panels called “boxPanels”:

The documentation for “boxPanels” can be accessed at this path:

layoutdoc/User_guide4_2.html

It is also possible to implement the functionality using the “uipanel” and programmatically controlling its size and clipping. For more details, this MATLAB Answers post might be helpful:

I hope it helps!
