How use Pop-Up Menu with including Check Box?
I would like to use Pop-Up Menu with Check Box.
In general, When I check PopUp Menu, then show the List.
But, I'd like to make List in CheckBox Style
Please give me some solution or answer.

A pop-up menu cannot include a check box (not unless perhaps you work at the Java level.)
You can have a push-button that turns on the visibility of a radiobutton group.

working java level means hard coding?
And if you have any example solution, could you provide it to me.

You can use a uicontextmenu, which has built-in checkmarks. It can be enabled by a left mouse click on any other uicontrol, e.g. a button. The position of the uicontextmenu should be set relative to the button to let it look more as a popup menu:
FigH = figure;
PopH = uicontextmenu('Parent', FigH);
uimenu(PopH, 'Label', 'Unchecked');
uimenu(PopH, 'Label', 'Checked', 'Checked', 'on');
ButtonH = uicontrol('Style', 'PushButton', 'Position', [20, 300, 60, 22], ...
'String', 'Click me', ...
'UIContextMenu', PopH, ...
'Callback', {@showMyPopup, PopH});
function showMyPopup(ButtonH, EventData, PopH)
Pos = get(ButtonH, 'Position');
set(PopH, 'Position', [Pos(1)-2, Pos(2)-1], 'Visible', 'on');
Currently this is a pop- down menu. At least it need no calls to undocumented functions.

CheckBoxListComboBox.png
Simple example of "CheckBoxListComboBox" usage:
f = figure;
% create CheckBoxListComboBox
jCB = com.jidesoft.combobox.CheckBoxListComboBox({'Item-1', 'Item-2', 'Item-3', 'Item-4', 'Item-5', 'Item-6', 'Item-7', 'Item-8'});
[hJavaCB, hJavaCBWrapper] = javacomponent(jCB, [], f); %#ok
set(hJavaCBWrapper, ...
'Units', 'pixels', ...
'Position', [4,4,460,20]);
set(hJavaCB, ... % modify CB properties
'ToolTipText', ...
['<html>Supports <b>multiple</b> selections via <i><font color="red">drop-down</font></i> list + OK, or by editing directly (but ensure ' ...
'<br /> correct spelling and that there is exactly one semicolon followed by at least one space "; " between items)</html>'], ...
'Name', 'Display range' ...
);
% direct access
hJavaCB.setSelectedIndices([0,1,4]);
xx = hJavaCB.getSelectedIndices(); % xx = [0,1,4]
% indirect access via model
jModel = hJavaCB.getModel();
sz = jModel.getSize(); % sz = 8
jModel.getElementAt(0); % ans = 'Item-1'
xx = jModel.getSelectedItem(); % ans = java.lang.Object[]: 'Item-2'; 'Item-5'; 'Item-8'. Use numel(xx), strcmp(xx(1),'Item-2'), etc
jModel.getIndexOf('Item-2'); % ans = 1
jModel.insertElementAt('Item-99', 3); % inserts between 'Item-3' (on pos 2) and 'Item-4' (on pos 3)
jModel.addElement('Item-100'); % append to end
%jModel.removeAllElements();
jModel.removeElement('Item-1');
jModel.removeElementAt(3);
jModel.setSelectedItem(['Item-5';'Item-6';'Item-7']);
hJavaCB.setFocusable(true);
hJavaCB.putClientProperty('TabCycleParticipant', true); % this may be unnecessary in some cases, but doesn't hurt
set(hJavaCB, ...
... % handles keys like VK_LEFT, etc
'KeyPressedCallback', {@callback_javaKeyPress}, ...
... % handles any selection changes, even temporary ones, before OK or Cancel!
'PropertyChangeCallback', {@callback_javaPropertyChange}, ...
... % handles only final selection changes, after Enter, OK or Cancel...
'ActionPerformedCallback', {@callback_javaActionPerformed} ...
);
% 'KeyPressedCallback' from hJavaCB
function callback_javaKeyPress(h, event)
switch event.getKeyCode()
case event.VK_LEFT
character = 'left';
otherwise
character = event.getKeyChar();
end
% character, event
end % function callback_javaKeyPress
% 'PropertyChangeCallback' from hJavaCB
function callback_javaPropertyChange(h, e)
%disp(' callback_javaPropertyChange ');
%h, e
%list = h.getSelectedIndices(); % not the indices are 0-based, and -1 means invalid field
%fprintf(1, 'callback_javaPropertyChange: ');fprintf(1, ' %d', list); fprintf(1, '\n');
end % function callback_javaPropertyChange
% 'ActionPerformedCallback' from hJavaCB
function callback_javaActionPerformed(h, e)
list = h.getSelectedIndices(); % not the indices are 0-based, and -1 means invalid field
fprintf(1, 'callback_javaActionPerformed: ');fprintf(1, ' %d', list); fprintf(1, '\n');
h, e
end % function callback_javaActionPerformed
Tested with 2017a and 2020a ...

Hi Daniel thanks for this wonderful tool. While running the code using Matlab 2021a version it gave me the following warning:
Warning: JAVACOMPONENT will be removed in a future release. For more information see UI Alternatives for MATLAB Apps on mathworks.com.
> In javacomponent (line 85)
In Popup_Checkbox (line 4)
I tried to find the alterantive using the following website
https://au.mathworks.com/products/matlab/app-designer/java-swing-alternatives.html
Could you please let me know whether do I need to work with UIfigure instead?
