The purpose of this option is to allow for custom suffixes based on the app block being used. It allows for the easy creation of specific brand pages e.g. by gender, where existing product search filters support by in link parameters.
This is in addition to the universal quick link settings within the app and also applies to collection mapping.
Remember - universal settings apply to all app blocks while this setting only applies to the specific app block it is added to.
Using redirect menus would require seperate collections for men and women
Using a compatible search mechanism there is no need for multiple collections as the filtering takes place on the collection page using a suffix parameter
Adding a suffix
Adding a new suffix can be done via the Theme customisation option for the following features - page, slider and icon.
Simply select a relevant app block and goto the Advanced Settings section
Then add the text value you wish to use or add a dynamic source value from a metafield
Now all brand links from this app block will have the following applied '&gender=male'.
Click save and repeat for other blocks you wish this setting on
Here is a sample setting for use as a metafield
Namespace & key: instant-brand-page.custom_filter
Type: Single line text
