First, open up your Webflow editor. Navigate to the page where you want to add the Event Calendar. You should see a screen that looks something like this.
Navigate to the page that you want to add the Event Calendar to. Use the page selector to do this.
We now need to add an Embed Component to the page. Click the add component button.
Then drag the Component to the part of the page that you want to add Event Calendar App to.
Paste your ECA embed code into the box that will now appear.
Click save and close. You will now see a grey box that says:
"'This <script> embed will only appear on the published/exported site.'".
As an extra, I added the 'container' class to my embed element. This will vary by Webflow site, but with my 'business starter' template this brings the embed in line with the rest of my content which is really nice. I also added some bottom margin to space the elements.
The final published result looks like this:
That's it! Event Calendar App will now appear on your Webflow site. Note, it will only appear on the published site and not in the editor.
