# Exercise 8.1: Add an external link field

In this exercise we’ll add a new link field to the *Job Posting* content type. The link will go to “More information” on another website.

## Add the link field

1. Go to *Structure* → *Content types* → **Job Posting** and click on the **Manage fields** tab.
2. Add a new field and use the following settings:

3. Click **Save and continue.** This will take you to the Field settings page.
4. There are no changes so just click **Save settings**.
5. This takes you to the settings for this field on the *Job posting* content type.

## Test it

Go to a Job posting and search for the 'More information' section and **Link** field.

## Change the field settings to make link title required field

2. Edit the Link field.
3. Change the Allow link text to “Required”.
4. Save settings.

## Re-test it

1. Update your Job posting content page from the previous example and enter the link title.
2. Compare the look of the content page.

The **More information** fields should now be required fields.
