<h2>Arguments</h2>
<dl><dt id="arg--">...<a class="anchor" aria-label="anchor" href="#arg--"></a></dt>
<dd><p>UI objects to put in each row/column cell; each argument will
occupy a single cell. (To put multiple items in a single cell, you can use
<code><a href="https://rstudio.github.io/htmltools/reference/tagList.html" class="external-link">tagList()</a></code> or <code><a href="https://rstudio.github.io/htmltools/reference/builder.html" class="external-link">div()</a></code> to combine them.) Named
arguments will be used as attributes on the <code>div</code> element that
encapsulates the row/column.</p></dd>
<dt id="arg-flex">flex<a class="anchor" aria-label="anchor" href="#arg-flex"></a></dt>
<dd><p>Determines how space should be distributed to the cells. Can be a
single value like <code>1</code> or <code>2</code> to evenly distribute the available
space; or use a vector of numbers to specify the proportions. For example,
<code>flex = c(2, 3)</code> would cause the space to be split 40%/60% between
two cells. NA values will cause the corresponding cell to be sized
according to its contents (without growing or shrinking).</p></dd>
<dt id="arg-width-height">width, height<a class="anchor" aria-label="anchor" href="#arg-width-height"></a></dt>
<dd><p>The total amount of width and height to use for the
entire row/column. For the default height of <code>"100%"</code> to be
effective, the parent must be <code>fillPage</code>, another
<code>fillRow</code>/<code>fillCol</code>, or some other HTML element whose height is
not determined by the height of its contents.</p></dd>
</dl></div>
<div id="details">
<h2>Details</h2>
<p>If you try to use <code>fillRow</code> and <code>fillCol</code> inside of other
Shiny containers, such as <code><a href="sidebarLayout.html">sidebarLayout()</a></code>,
<code><a href="navbarPage.html">navbarPage()</a></code>, or even <code>tags$div</code>, you will probably find
that they will not appear. This is due to <code>fillRow</code> and <code>fillCol</code>
defaulting to <code>height="100%"</code>, which will only work inside of
containers that have determined their own size (rather than shrinking to
the size of their contents, as is usually the case in HTML).</p>
<p>To avoid this problem, you have two options:</p><ul><li><p>only use <code>fillRow</code>/<code>fillCol</code> inside of <code>fillPage</code>,
<code>fillRow</code>, or <code>fillCol</code></p></li>
<li><p>provide an explicit <code>height</code> argument to
<code>fillRow</code>/<code>fillCol</code></p></li>
</ul></div>
