Introduction
The edit text widget provides a user interface in the browser for editing text tiddler fields. The editing element is dynamically bound to the underlying tiddler value: changes to the tiddler are instantly reflected, and any edits are instantly propagated.
By default, applying the EditTextWidget to the text
field of a tiddler will generates an HTML <textarea>
element, i.e. a multi-line editor. Applying the EditTextWidget to any other field generates an HTML <input type="text">
element, a single-line editor. This behaviour can be overridden with the tag
and type
attributes.
Content and Attributes
The content of the <$edit-text>
widget is ignored.
Attribute | Description |
---|---|
tiddler | The tiddler to edit (defaults to the current tiddler) |
field | The field to edit (defaults to text ). Takes precedence over the index attribute |
index | The index to edit |

focusSelectFromStart | Introduced in v5.2.6 If the focus attribute is enabled, determines the position of the start of the selection: 0 (default) places the start of the selection at the beginning of the text, 1 places the start of the selection after the first character, etc. |
focusSelectFromEnd | Introduced in v5.2.6 If the focus attribute is enabled, determines the position of the end of the selection: 0 (default) places the end of the selection at the end of the text, 1 places the start of the selection before the final character, etc. |
tabindex | Sets the tabindex attribute of the input or textarea to the given value |
autocomplete | Introduced in v5.1.23 An optional string to provide a hint to the browser how to handle autocomplete for this input |
tag | Overrides the generated HTML editing element tag. For a multi-line editor use tag=textarea . For a single-line editor use tag=input |
type | Overrides the generated HTML editing element type attribute |
size | The size of the input field (in characters). This exact result depends on browser and font. Use the class attribute to style width for precise control |

Examples
If you wanted to change the field myconfig of the tiddler AppSettings, you could use an EditTextWidget to edit the field, and then show the result anywhere else by using {{AppSettings!!myconfig}}
. Note that this will create tiddler AppSettings if it doesn't already exist.
<$edit-text tiddler="AppSettings" field="myconfig"/><p/>
Value of ''myconfig'' : {{AppSettings!!myconfig}}
Text Selection
If the edit field already contains text or a default value is provided, you can use the focusSelectFromStart
and focusSelectFromEnd
attributes to only select part of the text when using focus="yes"
.
Partial selection when editing this tiddler's caption field:
<$edit-text tiddler=<<currentTiddler>> field="caption" focus="yes" focusSelectFromStart="5" />
Provide a dated heading for this example where only the placeholder (but not the date) is selected for easier text input:
<$edit-text tiddler=<<currentTiddler>> field="heading" size="25" focus="yes" focusSelectFromEnd="13" default={{{ [[Heading Text (]] [<now YYYY-0MM-0DD>] [[)]] +[join[]] }}} />
Input Actions, with class attribute
\procedure onInput()
<%if [get[temp]match[$:/]] %>
<$action-confirm $message="Yes, this is how system tiddler names begin!"/>
<% endif %>
\end
Type a new tiddler name, starting with the system prefix `$:/`: <$edit-text inputActions=<<onInput>> field="temp" class="tc-edit-texteditor"/>
