It seems like you're using a high DPI monitor.

Please, try using a 100% scale in your screen settings to see if the context menu appears in the right position.

I just tested the DevTools in the MiniBrowser demo with a 125% screen scale and the context menu is in the right position. I use Delphi 12.

Not because of that.
I can have menu like the below. But if I selet a text such as in deltools that was typed or in an element, I cannot get menu such as copy and past.

Perhaps this is caused by the paste protection in the DevTools that was enabled by default several months ago.

But I still use "109.1.18+gf1c41e4+chromium-109.0.5414.120"
I can use ctrl+V or C, but just cannot use mouse menu.
Is that menu was controlled by itself?

Chromium decides which menu items are included by default in that context menu.

If there some way to activate context menu of text for copy or past in devtools.

I only know of two ways to enable pasting in the devtools :

1. Typing in console "allow pasting" and hit enter.

2. Modifying Chromium's source code and building a custom version of the CEF binaries.

How to add menu? Thank you!

I'm sorry but I'm not a c++ developer and modifying Chromium's code is outside the scope of the CEF4Delphi project.

But the problem is why it cannot have this menu when a text is selected in console and right click was done by create devtools in cef4.
BriskBard and chrome all can have this menu when a text is selected in console and right click was done.
