Multisite Site Index

Sites can be hidden from the list by adding an excluded argument to the shortcode, or with the option in the widget settings. Use a comma-separated list of site IDs. To find a site’s ID, look at the url for editing a site in the network admin. For example, the shortcode would be [site-index excluded="11,14,15,16"].

On networks with more than 100 sites, a number of sites option is available. Keep in mind that showing more sites may cause issues with server/database resources on very large networks. Shortcode usage: [site-index number="200"].

This plugin does its best to work with every theme out of the box, but you may need to make tweaks to make it look better. Use the CSS functionality in the customizer (available in WordPress 4.7 and newer) to style the list container .site-index, the individual site list item containers .site-index .site, or individual elements such as .site-index-site-title, .site-index-site-tagline, or site-index-site-icon. A few complete examples follow.

To display the site index in multiple columns, add this CSS in the customizer (using WordPress 4.7 or newer):

.site-index .site {
    width: 48%;
    float: left;
    margin: 0 2% 1em 0;
    padding: 0;
}

ul.site-index {
    list-style: none;
    margin: 1em 0;
    padding: 0;
    overflow: hidden;
}

.site-index .site-index-site-tagline {
font-size: .8em;
}

There are two ways to make sure the height of the icon matches the height of the site title – changing the icons to match the font size (Requires knowing the line-height used by your theme):

.site-index .site-index-site-icon {
    height:1.5em;
    width: 1.5em;
}

Or, you can set the font size and line height of the titles to match the icons:

.site-index .site-index-site-title {
    font-size: 24px;
    line-height: 32px;
}

.site-index {
list-style: none;
}

.site-index .site {
    margin: 1em 0 0 0;
}
