    <p>most bookmarklets that do something complecated like "creating a toolbar" simply add an external script to the page that the bookmarklet is invoked on.</p> <p>Basically all you have to do is write a link that contains javascript, which can be acheived by starting the <code>href=""</code> with <code>javascript:</code></p> <p>so lets just start with a script in an href that will add an external JavaScript to your page</p> <pre><code>addScript = function ( url ) { myScript = document.createElement('script'); myScript.src = "url"; document.head.appendChild(myScript); }; addScript("http://google.com/"); </code></pre> <p>so if you shrink that down into a url you get..</p> <pre><code>&lt;a href="javascript:addScript=function(url){myScript=document.createElement('script');myScript.src=url;document.head.appendChild(myScript);};addScript('http://google.com/');"&gt; click to add toolbar &lt;/a&gt; </code></pre> <p>however you want to make this bookmark-able so theres one more level of confusion we have to add... and this part has to be done in different ways depending on the browser </p> <pre><code>addBookmark( url, title ) { if (window.sidebar) { // Firefox window.sidebar.addPanel(url,bookmarkName,""); } else if(window.external) { // IE window.external.AddFavorite(url,bookmarkName); } } </code></pre> <p>You can include that on the page where you're going to have your add bookmark button. A couple things to note though</p> <ol> <li>this isnt going to work in opera.. but who cares about opera</li> <li>webkit browsers (chrome &amp; safari) dont allow javascript to create bookmarklets</li> </ol> <p>Finally you need to mash it all up into one ugly link</p> <pre><code> &lt;a href="javascript:addBookmark(\"javascript:addScript=function(url){myScript=document.createElement('script');myScript.src=url;document.head.appendChild(myScript);};addScript('http://google.com/');\",\"whatever you want the bookmarks name to be\")"&gt; click to add bookmark &lt;/a&gt; </code></pre> <p>In the end though I suggest you look into making a <a href="http://code.google.com/chrome/extensions/index.html" rel="nofollow"><strong>Google Chrome Extension</strong></a> or a <a href="https://developer.mozilla.org/en/extensions" rel="nofollow"><strong>Firefox Plugin</strong></a> instead of a bookmarklet since you have more capability with either of the two.</p> <p>As far as how to make a toolbar with JavaScript, well you're just going to have to make another question for that.. Its too much and you haven said enough about what you wan to do for me to answer it here.</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.
