    <p>Anyone know good sample code using jQuery UI's autocomplete widget that can autocomplete words in the middle of a text box, not just autocomplete of the word at the end only? </p> <p>I'm using the jquery UI autocomplete widget for a component that supports entry of multiple tags. It's like like stack overflow's tag editor, but simpler: no fancy formatting in the autocomplete dropdown, no "tag" background images in the edit box. I started with the <a href="http://jqueryui.com/demos/autocomplete/#multiple" rel="nofollow noreferrer">jQuery UI Autocomplete Multiple sample</a> and modified it. </p> <p>It's working OK, except autocomplete doesn't work for tags in the middle of a multi-tag string. For example, if I type <code>C Fortran</code> and then put the caret right after <code>C</code> and type <code>+</code>, I'd expect to see <code>C++</code> in the autocomplete list but instead I see <code>Fortran</code> again. </p> <p>Here's the code so far: <a href="http://jsfiddle.net/WCfyB/4/" rel="nofollow noreferrer">http://jsfiddle.net/WCfyB/4/</a></p> <p>This is the same problem described by <a href="https://stackoverflow.com/questions/7089406/autocomplete-in-middle-of-text-like-google-plus">autocomplete in middle of text (like Google Plus)</a>, but the problem in that question was simpler because he could rely on an empty <code>@</code> in the text to signal when to show the autocomplete. In my case, I can't just rely on the text-- I actually need to find out where the caret is and autocomplete for the word where the caret is. </p> <p>I could build this myself using caret or another plugin, but was wondering if there was already a jQuery-UI-based sample online that I could use without re-inventing another wheel, especially if there are browser-specific corner cases to worry about. Ideally, it'd behave like this: whenever the user places the caret inside or at the end of a tag (where tags are always separated by 1+ spaces), autocomplete is shown for that tag. Know a good sample?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
