Do you need to be able to select multiple bits of text but a repeater field is overkill? Use the tag-it field. This plugin brings uses ACF 5’s built-in Select2 library.
This field currently includes the following options:
<ul>
<li>available tags : Used as source for the autocompletion.</li>
</ul>
The jQuery UI plugin used in the first version of this plugin can be found here: https://github.com/aehlke/tag-it

Customize WordPress with Global Custom Fields! You can use GCF for example to create HTML + PHP shortcodes, global text fields, to save custom urls and retrieve them wherever you want and much more.
Add global fields in GCF Admin Page Create groups in the ‘Settings’ section and related fields in the ‘Fields’ section. Then edit the fields individually from the ‘GCF’ section.
Recover GCF with php Fields groups / single gcf can be retrieved anywhere within your theme / plugin with the function <code>get_gcf($group, $single = false, $eval = false)</code>
Show single GCF with a shortcode Load and display your single gcf with a shortcode! <code>[gcf group="group_name" field="field_name" eval=false]</code>
Each field is validated before saving. Add non-standard HTML tags and attributes in the “Settings” section if you need.
N.B. Use php “eval” only if you know what you’re doing. Save php fields using pseudo tags <code>[php] ... [/php]</code>
