To set character limits for inputs in a form in Webflow and make the placeholder text disappear once the input field is clicked on, you can use custom code and interactions. Here's how you can achieve this:

  1. Create a form in Webflow: Start by adding a form element to your Webflow project. Inside the form, add an input field that you want to set character limits for.

  2. Add custom code to limit characters: Select the input field, go to the settings panel on the right, and give the input field a unique class name under the "Class" field. Then, go to the "Custom Code" tab in the project settings.

  3. Inside the "Head Code" section, add the following JavaScript code:

<script>document.addEventListener('DOMContentLoaded', function() {  var inputElement = document.querySelector('.your-unique-class'); // Replace '.your-unique-class' with the class name you assigned to your input field  var maxCharacters = 50; // Change this number to set your desired character limit    inputElement.addEventListener('input', function() {    if (this.value.length > maxCharacters) {      this.value = this.value.substring(0, maxCharacters); // Truncate the input value if it exceeds the character limit    }  });});</script>
  1. Make the placeholder text disappear on click: Now, you'll need to add an interaction to hide the placeholder text when the input field is clicked on. Here's how you can do it:
  • Select the input field and go to the "Interactions" tab in the settings panel.
  • Click on the "+ New Interaction" button and choose the "Mouse Click" trigger.
  • Under the "Actions" section, click on the "+ New Action" button and choose "Affect Different Element".
  • From the dropdown menu, select the input field again and choose "Hide" as the action.
  • Finally, make sure to set the interaction to "affect different element on click" so that the placeholder text will disappear when the input field is clicked on.

Now you have successfully set character limits for an input in a form in Webflow and made the placeholder text disappear once the input field is clicked on.
