+ * Autoselect Typed plugin for Tomselect
+ *
+ * This plugin allows automatically selecting an option matching the typed text when the Tomselect element goes out of
+ * focus (is blurred) and/or when the delimiter is typed.
+ *
+ * #select_on_blur option
+ * Tomselect natively supports the "createOnBlur" option. This option picks up any remaining text in the input field
+ * and uses it to create a new option and selects that option. It does behave a bit strangely though, in that it will
+ * not select an already existing option when the input is blurred, so if you typed something that matches an option in
+ * the list and then click outside the box (without pressing enter) the entered text is just removed (unless you have
+ * allow duplicates on in which case it will create a new option).
+ * This plugin fixes that, such that Tomselect will first try to select an option matching the remaining uncommitted
+ * text and only when no matching option is found tries to create a new one (if createOnBlur and create is on)
+ *
+ * #select_on_delimiter option
+ * Normally when typing the delimiter (space by default) Tomselect will try to create a new option (and select it) (if
+ * create is on), but if the typed text matches an option (and allow duplicates is off) it refuses to react at all until
+ * you press enter. With this option, the delimiter will also allow selecting an option, not just creating it.

+/**
+ * click_to_edit plugin for Tomselect
+ *
+ * This plugin allows editing (and selecting text in) any selected item by clicking it.
+ *
+ * Usually, when the user typed some text and created an item in Tomselect that item cannot be edited anymore. To make
+ * a change, the item has to be deleted and retyped completely. There is also generally no way to copy text out of a
+ * tomselect item. The "restore_on_backspace" plugin improves that somewhat, by allowing the user to edit an item after
+ * pressing backspace. However, it is somewhat confusing to first have to focus the field an then hit backspace in order
+ * to copy a piece of text. It may also not be immediately obvious for editing.
+ * This plugin transforms an item into editable text when it is clicked, e.g. when the user tries to place the caret
+ * within an item or when they try to drag across the text to highlight it.
+ * It also plays nice with the remove_button plugin which still removes (deselects) an option entirely.
+ *
+ * It is recommended to also enable the autoselect_typed plugin when using this plugin. Without it, the text in the
+ * input field (i.e. the item that was just clicked) is lost when the user clicks outside the field. Also, when the user
+ * clicks an option (making it text) and then tries to enter another one by entering the delimiter (e.g. space) nothing
+ * happens until enter is pressed or the text is changed from what it was.
