[tw5] Re: Filter display of Dictionary List items based on tiddler's field??
I'll think about that. Sometimes I may want to select and copy the text.
I'll have to think of which I want to do more.
Thanks!!

One final tweak to the code:
instead of:
```
<$checkbox index=<> checked="1" unchecked="0"/> <>
```
I suggest putting the item text within the body of the $checkbox widget,
like this:
```
<$checkbox index=<> checked="1" unchecked="0"> <>
```
This allows you to click on the item text to toggle the checkbox.

Thanks!
That is perfect!. I think I have several other pages that can enjoy this
kind of feature, as well.

The problem is due to the surrounding `<$tiddler tiddler="Dictionary
Tiddler">... ` widget.
Because of this, the reference to `{!!searchText}` is looking in
"Dictionary Tiddler" for the field contents.
One way around this is to remove the `$tiddler` widget and hard-code the
"Dictionary Tiddler" title, like this:
```
<$list filter="[[Dictionary
Tiddler]indexes[]search:title:literal{!!searchText}sort[]]" variable=item>
<$checkbox tiddler="Dictionary Tiddler" index=<> checked="1"
unchecked="0"/>
<>
```
This allows the `{!!searchText}` reference to point to a field in the
tiddler containing the `<$list>` widget, rather than the "Dictionary
Tiddler" itself.
However... if the intention is to eventually enable lookups using different
Dictionary Tiddlers, then the following code may be more useful:
```
<$edit-text field="searchText"/>
<$select field="dictionary">
Dictionary Tiddler
Another Dictionary
Some Other Dictionary
etc...
<$let searchText={{!!searchText}}>
<$tiddler tiddler={{!!dictionary}}>
<$list
filter="[all[current]indexes[]search:title:literalsort[]]"
variable=item>
<$checkbox index=<> checked="1" unchecked="0"/>
<>
```
Basically, this sets a variable to the value of the searchText field before
using `$tiddler` to change the current tiddler,
and then uses the value of that variable in the filter syntax. It also
lets you select a dictionary tiddler title from a
droplist input, and then uses that title in the `$tiddler` widget, so that
the lookup points to another dictionary while
still using the searchText input from the current tiddler.
enjoy,

Thanks for replying. I'll note that other forum for future questions.
But it seems your code snippet is not working with the variable/field in
there. It works fine when I put some static text there, though, as seen in
my line above.
