Shash,
I've achieved this using the following: It creates a tiddler that holds tags for your checklist items.
Create a tiddler called "checklist" with the following content
\define checklist()
<$checkbox tiddler="$:/_cpa/Data/todos" tag="todo:$(currentTiddler)$">
<$link to="$(currentTiddler)$" tooltip="Create new detailed task">
$(currentTiddler)$
</$link>
</$checkbox>
\end
<$macrocall $name="checklist" />
I have a much more functional version called "tasks" that stores the items text; allows you to take notes on your checklist items; allows you to list the items separately here:
