How to set a data atributte with yii2 menu widget uikit - php

Question

i'm working with yii2 and uikit. i'm trying to build a navbar with the menu widget and i have this:
<nav class='uk-navbar'>
<?php
echo Menu::widget([
'activateItems' => true,
'activateParents' => true,
'activeCssClass' => 'uk-active',
'encodeLabels' => false,
'items' => [
['label' => 'Inicio', 'url' => ['site/index']],
['label' => 'Juridico', 'url' => ['juridico/index']],
['label' => 'Pagos', 'url' => ['pagos/index']],
['label' => 'Universidades', 'url' => ['universidades/index']],
['label' => 'Usuarios', 'url' => ['usuarios/index']],
['label' => 'Planes', 'options' => ['class' => 'uk-parent', 'data' => 'uk-dropdown'], 'url' => ['#'], 'items' => [
['label' => 'Planes Juridico', 'url' => ['#']],
['label' => 'Planes Universidades', 'url' => ['#']],
]],
['label' => 'Login', 'url' => ['site/login'], 'visible' => Yii::$app->user->isGuest],
],
'submenuTemplate' => '<div class="uk-dropdown uk-dropdown-navbar"><ul class="uk-nav uk-nav-navbar">{items}</ul></div>',
'options' => [ 'class' => 'uk-navbar-nav'],
]);
?>
</nav>
all i'm missing is this attribute but i don't know how to set it 'data-uk-dropdown'
i need this result in order to the dropdown to work:
<nav class="uk-navbar">
<ul class="uk-navbar-nav">
<li class="uk-active">Active</li>
<li>Item</li>
<li class="uk-parent" data-uk-dropdown>
Parent
<div class="uk-dropdown uk-dropdown-navbar">
<ul class="uk-nav uk-nav-navbar">
<li>Item</li>
<li>Another item</li>
<li class="uk-nav-header">Header</li>
<li>Item</li>
<li>Another item</li>
<li class="uk-nav-divider"></li>
<li>Separated item</li>
</ul>
</div>
</li>
</ul>
</nav>
Thanks in advance.

Answer 1

have you try to add in the 'options' like below?
<?php
echo Menu::widget([
'activateItems' => true,
'activateParents' => true,
'activeCssClass' => 'uk-active',
'encodeLabels' => false,
'items' => [
['label' => 'Inicio', 'url' => ['site/index']],
['label' => 'Juridico', 'url' => ['juridico/index']],
['label' => 'Pagos', 'url' => ['pagos/index']],
['label' => 'Universidades', 'url' => ['universidades/index']],
['label' => 'Usuarios', 'url' => ['usuarios/index']],
['label' => 'Planes', 'options' => ['class' => 'uk-parent', 'data' => 'uk-dropdown'], 'url' => ['#'], 'items' => [
['label' => 'Planes Juridico', 'url' => ['#']],
['label' => 'Planes Universidades', 'url' => ['#']],
]],
['label' => 'Login', 'url' => ['site/login'], 'visible' => Yii::$app->user->isGuest],
],
'submenuTemplate' => '<div class="uk-dropdown uk-dropdown-navbar"> <ul class="uk-nav uk-nav-navbar">{items}</ul></div>',
'options' => [
'class' => 'uk-navbar-nav',
'data-uk-dropdown' => ''
],
]);
?>

I think this is how you can add data attributes same method would work in other Yii2 places. So you specify the key 'data' and then add an array of just the attribute names (without prefixing them with 'data'. You can read more about it here.
NavBar::begin([
'options' => [
'id' => 'main-nav-bar',
'class' => 'navbar-inverse',
'data' => ['my-attribute' => 'myValue'] // This line specifically.
],
'innerContainerOptions' => ['class' => 'container-fluid']
]);
