You can set up filters on your portal/view so that people can switch between different categories by clicking different buttons. These 'filters' can be Airtable views that are reflected in your portal.
To set different predefined filters which portal users can choose from, go to:
Each custom view allows you to set a label, aiding users in recognizing the predefined filter they are using. If you prefer using an Airtable View for filtering and sorting, you can use the Airtable View name as the custom view's label.
Selecting Set custom settings in Filtering and Sorting will allow you to display personal or all the records. Adding filters and sorting conditions are also possible.
Only by setting a custom view other than Custom View 1 will the choices of predefined filters show up in the portal. You can add more in the extension settings.
