Hello Krishna,

I assume you want to link forms or different sections of a GUI using a popup menu in MATLAB. It involves creating a callback function that responds to changes in the popup menu selection. This function can then update the GUI to display the appropriate form or section based on the user's choice.

Here's a step-by-step example of how you can implement this:

Example: Linking Forms with a Popup Menu

Let's create a simple GUI with a popup menu that switches between different forms (or panels) based on the user's selection.

Step-by-Step Implementation

1. Create the Main GUI Window: Use uifigure to create the main window.
2. Add a Popup Menu: Use uidropdown to create a popup menu with options.
3. Create Panels for Each Form: Use uipanel to create separate panels for each form or section.
4. Link the Popup Menu to the Panels: Use a callback function to display the appropriate panel based on the popup menu selection.

Here is the example that you can follow:

function formSwitcher
    % Create main figure
    fig = uifigure('Name', 'Form Switcher', 'Position', [100, 100, 400, 300]);

    % Create a dropdown menu
    dropdown = uidropdown(fig, ...
        'Position', [150, 250, 100, 22], ...
        'Items', {'Form 1', 'Form 2', 'Form 3'}, ...
        'ValueChangedFcn', @(src, event) switchForm(src, fig));

    % Create panels for each form
    panel1 = uipanel(fig, 'Title', 'Form 1', 'Position', [50, 50, 300, 180]);
    uilabel(panel1, 'Text', 'This is Form 1', 'Position', [100, 80, 100, 22]);

    panel2 = uipanel(fig, 'Title', 'Form 2', 'Position', [50, 50, 300, 180], 'Visible', 'off');
    uilabel(panel2, 'Text', 'This is Form 2', 'Position', [100, 80, 100, 22]);

    panel3 = uipanel(fig, 'Title', 'Form 3', 'Position', [50, 50, 300, 180], 'Visible', 'off');
    uilabel(panel3, 'Text', 'This is Form 3', 'Position', [100, 80, 100, 22]);

    % Store panels in the figure's UserData for easy access
    fig.UserData = {panel1, panel2, panel3};

    % Callback function to switch forms
    function switchForm(src, fig)
        % Get the selected item
        selectedForm = src.Value;

        % Hide all panels
        panels = fig.UserData;
        for i = 1:length(panels)
            panels{i}.Visible = 'off';
        end

        % Show the selected panel
        switch selectedForm
            case 'Form 1'
                panels{1}.Visible = 'on';
            case 'Form 2'
                panels{2}.Visible = 'on';
            case 'Form 3'
                panels{3}.Visible = 'on';
        end
    end
end

I hope it helps!
