The "URL" custom field gives you the ability to add a link with customized Text, URL, Classes and more.
As you can see from the screenshot above, after selecting the "ACF - URL" type, the settings for this field will appear.
Let's see what each option does.
|Name||The name will be used to identify the field. Leave this blank and Joomla will fill in a default value from the title.|
|Label||The label of the field to display.|
|Description||A description of the field that will be displayed in the label tooltip.|
|Required||Is this a mandatory field?|
|Default Link Text||Set a link text to be used by default|
|Default Open in||Set the default way to open the link|
|URL Class||Customize your URL with your own CSS Classes|
|NoFollow||Selecte whether to add NoFollow attribute so search engines wont follow this link.|
|NoReferrer||Select whether to add NoReferrer attribute which wont send the HTTP referrer head so it won't be tracked by analytics tools.|
|Treat as Download Link||Select whether to download the file instead of navigating to the link.|
Once you are in your Article's Edit screen, choose the "Fields" Tab to see the URL custom field as you can see in the screenshot below.
In the input field, you can enter the text of the link, the URL as well as how to open the link(same tab, new tab or new window).
Take a look at the screenshot below to see how it could be displayed in your frontend.
