By default, the widget wizard in Access Collins will only allow you to set the widget for the site you are looking at or all sites.
It's possible to edit the widget code so that the widget displays the sites you want.
To do this you have to create a widget code for all of your sites:
Click Settings, Sites and choose then choose any site.
Click booking widget & links from the left-hand menu.
Scroll down to the widget wizard and select that you would like the widget to Show all of the sites in your organisation.
When you have finished editing, take your widget code from the grey box at the bottom of the page.
📌Note: Within the widget code you will see venue= , containing all the site IDs.
You just need to delete the sites from the widget code for the sites that you do not wish to be shown on the booking widget.
Copy the widget code and add it to your website.
