I'll create a simple component with two buttons using shadcn/ui:

This component includes:

1. Two buttons - one with the default style and one with an outline style
2. Responsive layout that stacks vertically on mobile and horizontally on larger screens
3. Proper spacing between the buttons
4. Centered alignment

The buttons use shadcn/ui's Button component which includes built-in accessibility features and styling. You can customize these buttons further by:

• Changing the variants (options include: default, destructive, outline, secondary, ghost, link)
• Adding icons
• Changing the size
• Adding click handlers for functionality

Would you like me to add any specific functionality or styling to these buttons?

I'll create a component with the interactive buttons as requested:

This component implements all the requested functionality:

1. Button A logs to the console when clicked
2. Button B opens a dialog when clicked
3. Inside the dialog, there's a button that opens a dropdown menu

4. The dropdown menu contains an item "Remove Button B" that, when clicked:

   • Unmounts Button B (by setting showButtonB to false)
   • Indirectly unmounts the dialog and dropdown (since they depend on Button B's existence)

To see it in action:

1. Click Button A to see console logs
2. Click Button B to open the dialog
3. Click the "Dropdown Menu" button in the dialog
4. Select "Remove Button B" from the dropdown to see Button B disappear along with the dialog

The component uses React's useState hooks to manage the visibility state of Button B and the dialog. When Button B is removed, the dialog automatically closes because its open state is tied to both the dialog's own state and the existence of Button B.
