Just want to open a link in a New tab

To open a dynamic link in a new tab, you can use the HTML "target" attribute. You would need to modify the code you provided to include this attribute. Here's how you can do it:

  label: "Ticket Id",
  value: a!richTextDisplayField(
    value: a!richTextItem(
      text: fv!row.issueId,
      link: a!dynamicLink(
        saveInto: {
          a!save(local!selectedTicketId, fv!row.issueId),
          a!save(local!showDetailsPage, true()),
          a!save(ri!showLinkedIssues, true()),
          a!save(ri!newShowDetailsPage, false())
        },
        linkStyle: "STANDALONE",
        attributes: {
          target: "_blank"  /* This opens the link in a new tab */
        }
      )
    )
  )
)

By adding the "target" attribute with the value "_blank," the link will open in a new browser tab or window when clicked.
