Hello !

Plz tell me how to change the background color of the system generated control's like search by category which we can add in our custom designing by just drag and drop .
i have one table in html designing whose background color is blue , and when i drag this control on that table that time due to the system generated control's background all design looks bad !
is there any solution to change the back ground color of such control's

You can change the background color of the right and left column by going to Design >> Site Design >> Style Settings. In here you will see a colors tab with options to change the right and left column.

If you are referring to the actual image you would need to do this through some sort of image editing software by downloading that image. Making the change and then reuploading the image with the same name.
