You can restrict the linked records options by adding a "<a href="https://miniextensions.com/filter-linked-records-in-miniextensions-form/" rel="nofollow noopener noreferrer" target="_blank">conditional filter</a>" to your field. When a filter is selected on the form, it will limit the linked records available in the list. The conditional filters for the form can only use the linked records field and lookup fields. To elaborate on this functionality, you can watch this video.

You can hide this filter from the field and use prefill to fill it up. You just need to set the Conditional linked record filtering fields type with the Hide filter fields (prefill using URL) option.

1. Click on the linked records field that you'd like to add filters to.
2. Go to the option under the Filtering &amp; Sorting Records section.

Nested linked fields are not supported on the legacy form. Learn more about this function's limits <a href="https://docs.miniextensions.com/en/articles/6242802-what-are-the-limitations-of-the-conditional-filter">here</a>.

Selecting an option from one dropdown should dictate the options available in the next field.
