# How to Use Hyperlinks

  1. Right-click on a layer, select Properties and go to the Attributes form tab.
  2. In the list of Available Widgets select the field you want to work with.
  3. In the Widget Display tab:
    • Ensure that Text Edit is selected
    • Check the Multiline and HTML options
  4. In the Defaults tab, use a string such as this as Default value:
    '<a href="https://www.lutraconsulting.co.uk/">Open link</a>'
    DETAILS

    The default value defines the hyperlink and how it will be displayed in the form using HTML:
    <a href="your link here">display text</a>
    Individual links can be generated for each feature based on a value from another field. Let's say there is a field called name with a sample value my-page:
    '<a href="'||'www.web-page.com/'||"name"||'">Open link</a>'' will result in www.web-page.com/my-page.

  5. If the link changes based on a value from a different field, check the Apply default value on update option.
  6. Apply the changes. Don't forget to save and sync your project!
