Hello,
It's possible, I can imagine process going something similar to this:
You would create a Edit Field (text) component where you would search the contents of DropDown Menu.
DropDown menu has two properties of interest, Value and Items. Items is a cell array that contains the options, where Value takes one of these options.
You can create a callback that would search for the Edit Field component text in Items. You can try with function contains (maybe better with regexp as Adam suggested, as I haven't worked with any of these). You will need to have a property/cell variable that will contain whole dataset for Items, replace it with filtered one when you type in something. When the Edit Field component is empty, then you can revert back to the whole dataset.
function ValueChangedFcn(app,event)
if isempty(app.TextToFind.Value) % If empty
app.DropDownMenu.Items = app.CompleteDropDownItems; % whole dataset
else
idx = contains(app.DropDownMenu.Items, app.TextToFind.Value)
Filtered_Values = app.DropDownMenu.Items(idx);
app.DropDownMenu.Items = Filtered_Values; % Consider a case as well when property Value is not in Items
% you'd get a warning or even an error
end
This is just a rough idea how would I do it, code above is not tested.
