How can i add new actions to identify feature context menu, i mean when selecting a feature with identify tool and right click on the selected feature, here i want to add new actions to the popup menu.
As far as I'm aware, there is no feature in QGIS that provide you with the ability to customize the
view feature form as shown in your image below, when you identify a feature. The only features that allow for customization is to follow up with selecting a auto open form, which will provide a dialogue box that could be edit if needed or view able in conjunction with the identify console box.
You may want to look in QT designer in creating a custom form that may be helpful in finding a solution.
