How can I hide these fields on Webflow if there is no CMS entry for them?

To hide fields in Webflow if there is no CMS entry for them, you can utilize conditional visibility settings. Here's a step-by-step guide to achieve this:

1. Select the element or field that you want to hide if there is no CMS entry.
2. In the right sidebar, under the "Settings" tab, click on the two circles icon to open the "Conditional Visibility" panel.
3. In the "Only When" dropdown menu, select "CMS Condition."
4. A sub-panel will appear where you can define the condition for hiding the element.
5. Click on the "Add New Condition" button.
6. In the condition setup, select the desired CMS field that you want to use as the condition.
7. Choose the comparison operator that suits your scenario, for example, "is set," "is not set," "is empty," "is not empty," etc.
8. Save your condition.
9. Now, the element will only be visible on the published site if the defined condition is met.

For example, let's say you have a CMS collection named "Blog" with a field called "Author." If you want to hide a paragraph element that displays the author's name when there is no author specified in a CMS entry, you can set up a conditional visibility condition like this:

1. Select the paragraph element that displays the author's name.
2. Open the "Conditional Visibility" panel in the right sidebar.
3. Choose "CMS Condition" and set up a new condition.
4. Select the "Author" field from the CMS collection.
5. Choose the "is not set" operator.
6. Save the condition.

Now, when the "Author" field is empty or not set in a CMS entry, the paragraph element will be hidden on the published site. It will only appear when there is a value in the "Author" field.

By using conditional visibility, you can create dynamic and personalized experiences based on the presence or absence of CMS data. This feature allows you to tailor content display and enhance the user experience on your Webflow site.
