Conditional properties

Firing events with properties depending on special conditions

Example:

navigation menu

Tagging:

A view is fired when the menu is opened, as well as a click is fired when a category is clicked by the user.
The nav click event should contain the clicked category.

Problem:

The walker is not able to recognize which category got clicked. The click event will always contain the first caught value. So the outcome will stay the same, even if the user clicks on different categories.

Describe the solution you'd like

The walker should be able to select the correct data in cases where multiple conditions are possible(click category A or click category B,..). So for the given example: The walker should only push the data of the clicked category and ignore everything else.
