 ### Filtering choice lists
 
 XLSForm allows you to filter option choice lists based on responses to previous questions. This feature, known as **choice filters**, can be used in various ways. For example, they can be used for **cascading select questions**, where the choice list for a child question (e.g., cities) is filtered based on the response to a parent question (e.g., country). They can also be used for filtering a multiple choice question to display only options selected in a previous question.

 For very large choice lists, containing hundreds or thousands of options, it is recommended to use `select_one_from_file` or `select_multiple_from_file` question types, which link a survey question to an **external file** containing the list of choices. This approach is more efficient than manually entering choices inside the XLSForm, helps avoid slow loading times and large XLSForms, and simplifies managing or editing extensive option sets.
