The UI for selecting multiple candidate can be customized through
<a href="snippet-reference.html#yas-prompt-functions"><code>yas-prompt-functions</code></a> , which defines your preferred methods of being
prompted for snippets.
</p>
<p>
You can customize it with
<code>M-x customize-variable RET yas-prompt-functions RET</code>. Alternatively you
can put in your emacs-file:
</p>
<div class="org-src-container">
<pre class="example">(setq yas-prompt-functions '(yas-x-prompt yas-dropdown-prompt))
<pre class="src src-emacs-lisp">(setq yas-prompt-functions '(yas-x-prompt yas-dropdown-prompt))
</pre>
</div>
<p>
Currently there are some alternatives solution with YASnippet.

The function <a href="snippet-reference.html#yas-x-prompt"><code>yas-x-prompt</code></a> can be used to show a popup menu for you to

YASnippet will list in this section all the loaded snippet definitions
organized by snippet table name.
</p>
<p>
You can use this section to explore currently loaded snippets. If you
click on one of them, the default behavior is to expand it,
unconditionally, inside the current buffer.
</p>
<p>
You can however, customize variable <a href="snippet-reference.html#yas-visit-from-menu"><code>yas-visit-from-menu</code></a> to be <code>t</code>
which will take you to the snippet definition file when you select it
from the menu.
</p>
<p>
If you want the menu show only snippet tables whose name corresponds to
a "real" major mode. You do this by setting <a href="snippet-reference.html#yas-use-menu"><code>yas-use-menu</code></a> to
'<code>real-modes</code>.
</p>
<p>
Finally, to have the menu show only the tables for the currently active
mode, set <a href="snippet-reference.html#yas-use-menu"><code>yas-use-menu</code></a> to <code>abbreviate</code>.
</p>
<p>
These customizations can also be found in the menu itself, under the
"Snippet menu behavior" submenu.

You may compile a top-level snippet directory with the
<code>yas-compile-directory</code> function, which will create a
<code>.yas-compiled-snippets.el</code> file under each mode subdirectory,
which contains definitions for all snippets in the subdirectory.
Compilation helps improve loading time.

Alternatively, you may compile all directories in the list
<code>yas-snippet-dirs</code> with the <code>yas-recompile-all</code> function.
