/**
|
|
* Refactors the table row markup to improve item label text wrapping.
|
|
*
|
|
* This addresses an issue specific to item labels that are long enough
|
|
* to be wrapped to a new line. Without this fix, a new line may start
|
|
* at the beginning of the table row, instead of the expected behavior of
|
|
* starting at the x axis of the first line.
|
|
*
|
|
* Addressing this issue requires changing the structure of a tabledrag
|
|
* cell's first row.
|
|
* @example
|
|
* <!-- Default tabledrag structure, which has the wrapping problem. -->
|
|
* <tr class="draggable">
|
|
* <td>
|
|
* <!--
|
|
* Indentations are next to each other because they are styled as
|
|
* `float: left;`
|
|
* -->
|
|
* <div class="indentation"></div>
|
|
* <div class="indentation"></div>
|
|
* <a class="tabledrag-handle"></a>
|
|
* <!-- If the text in this link wraps enough times that the element
|
|
* is taller than the floated elements preceding it, some lines
|
|
* will wrap to the beginning of the row instead of aligning with
|
|
* the beginning of the link text.
|
|
* -->
|
|
* <a class="menu-item__link">A longer label that may require wrapping</a>
|
|
* </td>
|
|
* <!-- etc. -->
|
|
* </tr>
|
|
* @example
|
|
* <!-- Claro tabledrag structure, this fixes the wrapping problem. -->
|
|
* <tr class="draggable">
|
|
* <td class="tabledrag-cell">
|
|
* <div class="tabledrag-cell-content">
|
|
* <!-- Indentations are next to each other because
|
|
* .table-drag-cell-content is styled as `display: table-row;`
|
|
* and .table-drag-cell-content > * is styled as
|
|
* `display: table-cell;`
|
|
* -->
|
|
* <div class="indentation"></div>
|
|
* <div class="indentation"></div>
|

* <a class="tabledrag-handle"></a>
|

* <div class="tabledrag-cell-content__item">
|
|
* <!-- Placing the link inside a div styled as
|
|
* `display: table-cell;` allows the text to wrap within
|
|
* the boundaries of the "cell".
|
