Repeating Units

Repeating units are a repeatable set of controls on the level of tabs. If you define a tab as repeatable the content defined in this tab can be repeated (progammatically or by the user) depending on the repeating options you set.

Note

Setting the attribute id in the second level navigation is mandatory for both, the repeating units as well as for the expandable content.

Repeating Unit (object notation)

<li
    id="tabRepeatingUnit"
    data-hf-title="Repeating Unit"
    data-hf-repeating='{
        "min": 1,
        "max": 10,
        "label": "Repeating Unit",
        "labelAdd": "Add",
        "labelRemove": "Remove",
        "anchors": true,
        "toolbar": true,
        "order": "desc",
        "showOnlyLastToolbar": true,
        "alwaysShowHeaderFooter": false,
        "header": ["repeating1HeaderBlock1","repeating1HeaderBlock2"],
        "footer": {
            "blocks": ["../DemoForm.templ/DemoForm.templ.html#repeating1FooterBlock1","../DemoForm.templ/DemoForm.templ.html#repeating1FooterBlock2"],
            "idPrefix": "ru1_",
            "phPrefix": "ru1_",
            "phPlaceholder1": "Footer Placeholder1",
            "phPlaceholder2": "Footer Placeholder2"
        }
    }'
></li>

Repeating Unit (attribute notation)

<!-- deprecated -->
<li
    id="tabRepeatingUnit"
    data-hf-title="Repeating Unit"
    data-hf-expandable="true"
    data-hf-repeatable="true"
    data-hf-repeatablemin="0"
    data-hf-repeatablemax="10"
    data-hf-repeatablelabel="New contact"
    data-hf-repeatablelabeladd="Add"
    data-hf-repeatablelabelremove="Remove"
    data-hf-repeatableheader="repeating1HeaderBlock1,repeating1HeaderBlock2"
    data-hf-repeatablefooter="repeating1FooterBlock1,repeating1FooterBlock2"
    data-hf-repeatablealwaysshowheaderfooter="true"
    data-hf-repeatableanchors="false"
    data-hf-repeatabletoolbar="true"
    data-hf-repeatableorder="desc"
    data-hf-repeatableshowonlylasttoolbar="true"
></li>

Important

Attribute notation is deprecated. Please use object notation instead.

alwaysShowHeaderFooter \ data-hf-repeatablealwaysshowheaderfooter**	string	"alwaysShowHeaderFooter"=true	Define if Header and Footer is always visible even if there are no RepeatingUnits.

* These options are required
** These options are deprecated

Very Important

In case of using the option "alwaysShowHeaderFooter"= false to hide Header and Footer you are not able to use the option required: true inside these blocks.

There are additionally several possibilities to offer the user a better overview within the repeating units:

Option 1: Use headings which include the block number calculated by the application.

<div class="grid column1">
    <div class="r1 c1">
        <h3>Contact #<span data-hf-bind="textContent: repeatableCount"></span></h3>
    </div>
</div>

Repeating Unit Counter

Option 2: Use "anchors": true to add linking anchors to the tab menu so the user can easily navigate to the selected repeating block.

Option 3: Use CSS-styling to provide a better overview when coloring every second repeating unit’s background.

formpage .main-content .sheet .repeatingunit:nth-child(odd) {
    background-color: lightgray;
}

Option 4: Use Includes to define header/footer blocks only once for multiple use in your Form Definition.

<li
    data-hf-repeating='{
    "footer": {
        "blocks": ["../DemoForm.templ/DemoForm.templ.html#repeating1FooterBlock1","../DemoForm.templ/DemoForm.templ.html#repeating1FooterBlock2"],
        "idPrefix": "ru1_",
        "phPrefix": "ru1_",
        "phPlaceholder1": "Footer Placeholder1",
        "phPlaceholder2": "Footer Placeholder2"
    }
}'
></li>

Note

In opposite to the inclusion of blocks inside not repeatable tabs you have to use idprefix instead of data-id-prefix, phPrefix instead of data-ph-prefix and ph[customValue] instead of data-ph-[customValue].
