/**
 * @module InfoTableItemArray
 * The `InfoTableItemArray` component handles arrays in the info-table-row component.
 * If an array has more than 10 items, then only 5 are displayed and a count of total items is displayed next to the five.
 * If a isLink is true than a link can be set for the use to click on the specific array item
 * If a wildcard is a potential variable in the string of an item, then you can use the modelType and wildcardLabel parameters to
 * return a wildcard count similar to what is done in the searchSelect component.
 *
 * @example
 * ```js
 * <InfoTableItemArray
 * @label="Roles"
 * @displayArray={{['test-1','test-2','test-3']}}
 * @isLink={{true}}
 * @rootRoute="vault.cluster.secrets.backend.list-root"
 * @itemRoute="vault.cluster.secrets.backend.show"
 * @modelType="transform/role"
 * @queryParam="role"
 * @backend="transform"
 * ```
 *
 * @param {string} label - used to render lowercased display text for "View all <label>."
 * @param {array} displayArray - The array of data to be displayed. (In InfoTableRow this comes from the @value arg.) If the array length > 10, and @doNotTruncate is false only 5 will show with a count of the number hidden.
 * @param {boolean} [isLink]  - Indicates if the item should contain a link-to component.  Only setup for arrays, but this could be changed if needed.
 * @param {string || array} [rootRoute="vault.cluster.secrets.backend.list-root"] -  Tells what route the link should go to when selecting "view all". If the route requires more than one dynamic param, insert an array.
 * @param {string || array} [itemRoute=vault.cluster.secrets.backend.show] - Tells what route the link should go to when selecting the individual item. If the route requires more than one dynamic param, insert an array.
 * @param {string} [modelType]  - Tells which model you want to query and set allOptions.  Used in conjunction with the the isLink.
 * @param {string} [wildcardLabel]  - when you want the component to return a count on the model for options returned when using a wildcard you must provide a label of the count e.g. role.  Should be singular.
 * @param {string} [backend] - To specify which backend to point the link to.
 * @param {boolean} [doNotTruncate=false] - Determines whether to show the View all "roles" link. Otherwise uses the ReadMore component's "See More" toggle
 * @param {boolean} [renderItemName=false] - If true renders the item name instead of its id
