What it is
The CSS selector field that tells ConversionBox where to render Instant Search results within the theme’s DOM (for example, replacing the default results container like #MainContent).
Why it matters
Correct selector mapping is the single most important technical step to ensure Instant Search integrates seamlessly into the theme without layout collisions or duplicate content rendering.
How to configure
Inspect your theme with browser devtools to locate the container element that holds search results or collection content (common IDs/classes: #MainContent, content, .main-column).
Copy a stable selector that uniquely identifies that container. Prefer IDs or classes that are unlikely to change with theme updates.
Paste the selector into ConversionBox’s CSS Selector setting and save.
Load a search result page and confirm ConversionBox is rendering in place of the theme content (no duplicated product lists).
