You need to apply the css styles to the k-list
css class. Can you please try to use the below css in order to set the background color of the search autocomplete list:
I have used the red color only as a sample. You can change it to the desired color.
If you would like to change the background of the item from the autocomplete list on hover you can use the .k-state-hover
Please note to use the !important
clause in order to make sure that your custom css styles will be applied.
You can also use the DevTools of your browser in order to inspect the css classes and default styles applied by to the autocomplete list and set your own css styles.
