 ## Description

 I want simple filtering options in the Grid filter menu - both for my uses and my backend. How do I remove the extra conditions so it behaves like the filter row and does not have extra and/or operators?

 There are two options:
 
 * Use a [custom filter template](slug:grid-templates-filter). It provides full flexibility over the interface and building the filter descriptor.
-* Use custom CSS to [override the theme](slug:themes-override) and hide the elements that provide the and/or secondary conditions. The example below demonstrates this approach. Note that **the required CSS is different for different UI for Blazor versions**:
