Hello, I am working on MATLAB Appdesigner. I am using Dropdown to select one option from the data. However, I need to group some options together. Can anyone help me out? I don't want to use list in appdesigner as all options are shown on the interface, I have more than 20 options under dropdown. I want to select 2-3 options together from the 20 options, and proceed further. I would be grateful for any suggestions. Thank you.

Hello,

there are few options that you can do:

Use dropdown to add items to the ListBox component. You would have to change DropDown value few times to add each item to ListBox.
If you want to have multiple selection at once, then Table component would be best as it allows so. Maybe you can figure out the way to expand and collapse the Table.
