PLEASE NOTE: This requires some HTML knowledge and a good understand of CoReg tech.
Your competition template supports the ability of a repeat tag, this tag allows you to loop through information for all your competitions and output it for users,
Example:
<repeat type="competition">
<img data-db-localized-src="COMPETITION_THUMBNAIL" />
<h2 data-db-localized-content="COMPETITION_NAME"></h2>
<a data-db-href="COMPETITION_URI">enter competition</a>
<span data-db-localized-content="COMPETITION_DESCRIPTION"></span>
Opens on <data name="COMPETITION_OPEN_ON" /><br />
Close on <data name="COMPETITION_CLOSE_ON">stuff</data><br />
Draw on <data name="COMPETITION_DRAW_ON" /><br />
</repeat>
AS you can see, this looks like normal HTML with the addition of a repeat tag and some data tags. But with those tags, the outputted code will render that for each competition.
Here's a breakdown of available options
An Image for the competition from COMPETITION_THUMBNAIL
The competition name from COMPETITION_NAME
A link to enter competition with the COMPETITION_URI
A description of the competition from COMPETITION_DESCRIPTION
And then details of when it opens, closes and when it will be drawn with
COMPETITION_OPEN_ON
COMPETITION_CLOSE_ON
COMPETITION_DRAW_ON
