Mario, Eric, Thanks for the quick reply, you gave me hope. Eric's answer seems closer to what I need, since I want to sort by field value not by tag. Typically I have a field named 'time' with possible value say 'early', 'late','never' and I want all tiddlers where time==late. However I cannot make the above script to work ! I get the following message
TypeError: store.displayTiddlers is not a function The script seems right though ... (I have installed the InlineJavascriptPlugin and checked that it is present). Scalpa (PS : I got disconnected from Google Groups when I first posted this, so I assumed it didn't go through; if it did I'm sorry for the double post ; erase at will) On 13 fév, 12:30, Eric Shulman <[email protected]> wrote: > > I’ve been trying to open multiple tiddlers as well and following > > closely the hints here (being a newbie).
