To hide select fields in Webflow based on the user's selected option, you can use custom code and interaction triggers.
Here's a step-by-step guide to achieve this:
1. Add a select field element to your Webflow project, and set the options as needed.
2. Give the select field a unique class name by selecting the element and going to the "Settings" panel on the right-hand side.
3. Within your Webflow project, go to the Project Settings by clicking on the gear icon in the top-right corner.
4. In the Project Settings, click on the "Custom Code" tab.
5. In the "Head" section of your custom code, add a `
```
Replace `.your-select-field-class` with the actual class name of your select field element. Also, replace `.your-hidden-elements-class` with the class name of the elements you want to hide/show based on the selected option.
7. Save the changes and publish your website.
Now, when the user selects a specific option in the select field, the associated elements will be hidden or shown based on your JavaScript code.
Note: Keep in mind that using custom code modifies the behavior of your Webflow project outside of the visual editor. Make sure to test and preview your changes in different browsers and devices to ensure a seamless user experience.
