Context menu goes off-screen when mouse is at right had side of screen.

[JoeK]

Create an editor instance that spans the with of the screen. Move the mouse to the right hand side of the editor and right click. Observe the context menu is partially rendered off screen. See attached screen shot. The context menu should be rendered to the left of the mouse.

Scroll bars are rendered so it can be accessed if the user moves to the right.

I faced the same problem and I did a workaround with this patch. Tested with IE8, FF3 and Chrome, only in 'ltr' situation.

Implement full off-screen support for context menu inspired by pomu's patch.

As discussed with Fred, we may even come out a "just work" solution which cascade float panels for off-screen, which is more implementation lightweight than the previous patch. Ticket Test added at :

It looks like page scrolling impacts on the calculations. In both IE and FF, the panel opens to the top if you scroll down the page and opens the context menu, even if there is room for it at the bottom of the cursor.

Nice catch indeed.

After patching, in FF:

1. Load a sample.
2. Click the color selector.
3. With the color selector opened, click any of the combos.

The color selector remains opened. It happens only on first opening, with all combinations of panels opening order, including the context menu.

In IE instead, the panels don't show on first click.

The activation function is been placed at wrong place in previous patch.

[fredck]

No change in IE. The panels are still not showing on first click.

[fredck]

I confirm that in IE8 the panels don't appear on first click.

Fixed with [4606].

This solution partially fixes the problem. The sub menu displays over the main menu, making it impossible to navigate around the context menu properly. The sub menu should really display to the side of the main menu.

The sub menu displays over the main menu...
