In the widgets list view, find the widget you created. Click on it to open the details page for management and customization.
On the widget details page, enable the Collection Pages option.
Choose how broadly the widget should appear:
If you choose Specific Collection Pages, continue to the next step. If you choose All Collection Pages, skip to Step 5.
Choose Specific Collection Pages, then click Select Collections. In Shopify’s collection picker, select one or more collections and click Select to apply them.
Once you’ve chosen the collection-page scope, click Save in Shopify’s Unsaved changes bar to save the widget display settings.
Open Shopify Admin -> Online Store -> Themes -> Customize. In the theme editor, switch to the Collection template.
Within the Collection template, click Add section, open the Apps tab, and select the Vizup app block. Adding the block is enough; you do not need to enter a widget name in the theme editor.
Click Save in the theme editor to apply the Collection template changes and make the widget live on your store.
