Displaying the nomination form
After configure an achievement or rank to accept nominations, you have 2 ways to display the nomination form:
1) On blocks (shortcodes and widgets) where an achievement or rank can be displayed you will get the option “Show Nominations” to display it.
For shortcodes, there will be the “nominations” attribute that accepts the “yes” or “no” values.
[gamipress_achievement id="123" nominations="yes"]
2) You can place a nomination form anywhere, including in-line on any page or post, using the [gamipress_nomination] shortcode or block.
Also, you can place a nomination form on any sidebar through widgets provided by this add-on.
