Below code convert your array to Ul li list.
// Build parent ul
function BuildMegaMenu($arr,$class = 'parent')
{
if(!empty($arr))
{
$html = "<ul class='p_category'>";
foreach($arr as $val)
{
if($val['mega_menu'] && !empty($val['children'])) // check for mega menu and children
{
// call sub helper function for procesing the children of children
// making a ul li with class
$rs = SubBuildMegaMenu($val['children'], 'parent');
if(!empty($rs)) {
$html .= "<li>";
$html .= "<div class='".$class."'>";
$html .= $val['title'];
$html .= $rs;
$html .= "</div>";
$html .= "</li>";
}
}
else {
$html .= "<li><div class='parent'>".$val['title']."</div></li>";
}
}
$html .= "</ul>";
return $html;
}
return false;
}
// Sub helper function for processing childrens
function SubBuildMegaMenu($arr, $class = 'parent')
{
if(!empty($arr))
{
$html = "<ul>";
foreach($arr as $val)
{
if($val['mega_menu'] && !empty($val['children'])) // check for mega menu and children
{
// call sub helper function for procesing the children of children
// making a ul li with class
$rs = SubBuildMegaMenu($val['children'], $class);
if(!empty($rs))
{
$html .= "<li>";
$html .= "<div class='".$class."'>";
$html .= $val['title'];
$html .= $rs;
$html .= "</div>";
$html .= "</li>";
}
}
else{
$html .= "<li><div class='parent'>".$val['title']."</div></li>";
}
}
$html .= "</ul>";
return $html;
}
}
