    <p>Unordered lists are often created with the intent of using them as a menu, but an <code>li</code> list item is text. Because the list <code>li</code> item is text, the mouse pointer will not be an arrow, but an "I cursor". Users are accustomed to seeing a pointing finger for a mouse pointer when something is clickable. Using an anchor tag <code>a</code> inside of the <code>li</code> tag causes the mouse pointer to change to a pointing finger. The pointing finger is a lot better for using the list as a menu.</p> <pre><code>&lt;ul id="menu"&gt; &lt;li&gt;&lt;a href="#"&gt;Menu Item 1&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Menu Item 2&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Menu Item 3&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Menu Item 4&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>If the list is being used for a menu, and doesn't need a link, then a URL doesn't need to be designated. But the problem is that if you leave out the <code>href</code> attribute, text in the <code>&lt;a&gt;</code> tag is seen as text, and therefore the mouse pointer is back to an I-cursor. The I-cursor might make the user think that the menu item is not clickable. Therefore, you still need an <code>href</code>, but you don't need a link to anywhere.</p> <p>You could use lots of <code>div</code> or <code>p</code> tags for a menu list, but the mouse pointer would be an I-cursor for them also.</p> <p>You could use lots of buttons stacked on top of each other for a menu list, but the list seems to be preferable. And that's probably why the <code>href="#"</code> that points to nowhere is used in anchor tags inside of list tags.</p> <p>You can set the pointer style in CSS, so that is another option. The <code>href="#"</code> to nowhere might just be the lazy way to set some styling.</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.
