Since I have more entries, I would like to put it in collapse mode in two categories. The example is shown below.
Could someone tell how to get similar feature of collapse/expand in MATLAB App designer?
We have referred this link https://in.mathworks.com/help/matlab/ref/uitree.html but the tree is opening a new window and not on the same panel.
Any help on this is highly appreciated.
Thanks,
Vijay

Hi Vijay,
As per my understanding you want to create a collapse and expand list inside the panel.
Find the components such as “Panel” and “Tree” in the “Component Library” of “AppDesigner” using which the expand/collapse list is created inside the panel.
In the above figure I have created two “Tree” inside the “Panel”.
The below figure shows the “Component Browser” structure for the above output in the “AppDesigner”
Please refer to the documentation link here for more information on "expand()" and "collapse()" function.
Also refer to the "AppDesigner" documentation for more information.
