Reviewer's GuideThis PR refactors the toggle logic for multi-select items by introducing a dedicated ToggleItem method, overloading ToggleRow to accept an index string for JS interop, and updating the component markup to pass item indices via data attributes, thereby restoring close-button functionality.

Pull Request Overview
This PR fixes an issue where the close button in the MultiSelectGeneric component was not working properly. The fix introduces a new overloaded ToggleRow method that accepts a string parameter for JavaScript invocation and separates the toggle functionality for different use cases.
- Introduces a new
ToggleRow(string val)method that can be called from JavaScript - Separates row toggling logic into
ToggleRowandToggleItemmethods for different contexts - Adds
GetValueStringmethod to provide string representation of item indices for popover scenarios

This creates infinite recursion. The method ToggleRow(string val) calls ToggleRow(item) which should be calling the private ToggleRow(SelectedItem<TValue> item) method instead.

This method only removes items and doesn't check the IsDisabled state, unlike the original ToggleRow implementation. Consider adding the disabled check for consistency.

**suggestion:** Handle non-integer or out-of-range values more explicitly.
Consider adding error handling or logging for invalid or out-of-range values to prevent silent failures and aid debugging.

<issue_to_address>
**suggestion:** Consider handling case where item is not in SelectedItems.
IndexOf returns -1 if the item is not found, which may not be appropriate for GetValueString. Consider returning null or a different sentinel value instead.
```suggestion
private string? GetValueString(SelectedItem<TValue> item)
{
if (!IsPopover)
{
return null;
}
var index = SelectedItems.IndexOf(item);
return index >= 0 ? index.ToString() : null;
}
```
