NOTE: If you want to add custom code snippets inside <head> element, or at the end of the page, before the <body> element closes, you can do that from Settings => Custom Code for application level changes or from Page Settings for page level modifications. This tutorial covers the cases when you want to add a code snippet anywhere inside the <body> element.
Custom code is added through the Custom Code block in Blocks => Custom Code.
Now, you can Preview your Softr app to see the changes.
Let's see how the Custom Code block works on a specific example. We'll use it to embed a Calendly widget within our Softr app.
In our Calendly account, we are going to navigate to Share Your Link in the Account dropdown menu.
In the pop-up that appears next, let's choose the embed option as shown below.
Next, we'll select Inline Embed and hit continue.
In the following screen, we can customize our Calendly widget, and, when we're done, we need to click Copy Code.
Finally, we will go back to our Softr app, paste the code in the Custom Code block, and hit Preview to see what it looks like.
