To display only a certain number of dates, include this style block on the page.
<style>
.seated-event-row:nth-child(n+6)
{display:none !important}
</style>
This example displays the next 5 dates. To change the number to display, just adjust the number after "n+". For example to show 10 dates, you'd write (n+11) instead of (n+6).
You can see this in action on Trace Adkins site.
Notes:
To display the preview, make to install your tour listings twice: once on the page with your tour preview with the above style line and once on your full tour page.
You'll want to include a button with a link to view all tour dates right below your limited preview. The way to add a button depends on your site, but you can find a broad overview here. Please reach out to your account manager with any questions!
