Does anyone know if the search field properties can be modified in the perspective property editor? I cannot find this in the OTB properties that appear or from the property list for the table object. I also did not find it in the list of properties that can be added with the add object member feature. in the image below the filter prop that is marked controls the object behind the text field but not the field itself.
What are you trying to change about this field?
the color of the highlight when the text is selected, for example if the text is 123456, and a user were to either double click on the text to select it or drag over the text to select it becomes highlighted. I want to control the color of the highlight. when applying a predefined style to this object it does not appear to pick up what is defined in the style drop down for the filter in props.
I can't give you a specific answer right now because I don't have ignition on this machine, but here's what I would do:
in your browser, open the dev tools (ctrl + shift + i) and use the inspector to select the search field (use this icon : 
)
Try to find something that can be used to target that element: a class, a specific hierarchy, etc
Once you have that, use the advanced style sheet to apply whatever css you want to the element.
