How to add link in readOnly grid.

I have used safelink for the same in readOnly grid.

But Bcoz I have used uri:" ",getting page for all the modules as same page,Do I have any option to provide the different urls for each modules(business,financial,account....etc shown in the fig).Since url not same for all modules here

What you have here will work, though I strongly suggest (in basically all cases) that developers avoid using a!linkField() and instead use a!richTextDisplayField(), subsequently making use of the "link" functionality contained down in a!richTextItem().  This approach is useful and more flexible in several ways - first, the link itself can conditionally be turned on or off depending on any factors you want (whereas a!linkField() will break if you try to not give it a link to refer to).  Secondly, you have full control over text formatting, icons, etc, as well as the link style itself (i.e. underlined or not).

a!gridColumn(
  label: "Link Column",
  value: a!richTextDisplayField(
    value: {
      a!richTextItem(
        text: fv!row.workflowDescription,
        link: a!safeLink(
          showWhen: local!showWebLinks,
          uri: "www.google.com"
        ),
        
        /* further style configuration options, for reference: */
        linkStyle: "STANDALONE",
        size: "MEDIUM",
        style: "EMPHASIS"
      )
    }
  ),
  width: "AUTO"
)

  width: "AUTO"
)

yes thank you,it is working.

Can we have the option to provide safelink for the  gridField label?

The label which is shown here is representing right side value,Do I have the option to provide link for that label?

All field labels, etc, can only display Plain Text.
