Multiple filters with tags
This extension allows you to easily add tags for the selected options of your filters. You can choose where to place the tags. They can be placed under each filter or in the same div. The data-tags-row attribute, which you add to each input, specifies the ID of the div where you want to display the tag.
The template for your tag is taken from a <template> tag. This allows you to easily modify the HTML structure of your tag without touching the JavaScript function.
Demo
Installation
Import the function into the JavaScript file of your project
import { MultipleFiltersWithTags } from "@overdog/fn"Create and initialize an instance
new MultipleFiltersWithTags("#filter-wrapper-tags", {
divIds: ["listing"]
}).init()
This element uses the same options and arguments as the Multiple choices filters.
