Here's one with a default setting: { "attribute":"WCI", "displayname":"Wild Card Icon", "displaytranslationkey":"wild-card-icon", "type":"select", "options":[ "⊛|⊛", "✪|✪", "♕|♕", "†|†", "༒|༒" ], "default":"✪", "description":"Select the Wild Card icon to be used in the Stat Block output.", "descriptiontranslationkey":"wild-card-icon-desc" } To set the Default state of the checkbox, you set the "default" to the actual value of the checkbox. If you didn't specify an actual value in the character sheet's HTML, then use "on" MagooChris said: Thanks for the replies, but the checkboxes I have are linked, but what I want to set is that when a new campaign is selected with the Character Sheet, I want some of the checkboxes in the Game Settings to show "Checked" by default. You can also accomplish this in the character sheet's HTML by simply setting it as checked. <input type="checkbox" class="sheet-useBackground" name="attr_background" value="1" checked />
