Performance problems when loading the map

Hi Daniel,
thanks for your reply. As an alternative solution to the performance problem I tryed to add this recommended java script (https://www.open-user-map.com/knowledge-base/trigger-map-actions-with-javascript/#activate-deactivate-a-marker-category) to the Custom JS:

// Function to get the value of a specific URL parameter
function getQueryParam(param) {
const urlParams = new URLSearchParams(window.location.search);
return urlParams.get(param);
}

// Get the 'oum-category' parameter value from the URL
const categoryNumber = getQueryParam('oum-category');

// Check if the 'oum-category' parameter is present
if (categoryNumber !== null) {
// Click all categories first
document.querySelectorAll('.oum-filter-list label').forEach((category) => {
category.click();
});

// Click specifically on the label based on the 'oum-category' value
// Convert categoryNumber to a 1-based index for :nth-child() selector
const categoryIndex = parseInt(categoryNumber, 10);
if (!isNaN(categoryIndex)) { // Ensure categoryNumber is a valid number
const targetLabel = document.querySelector(.oum-filter-list label:nth-child(${categoryIndex}));
if (targetLabel) {
targetLabel.click();
} else {
console.error('Specified category index is out of range.');
}
} else {
console.error('Invalid category number specified in the URL parameter.');
}
}

The script doesn’t work even when I add ?oum-category=3 to the page load:
https://neu.muenzenwoche.de/institutionen/?oum-category=3

Any idea?
Best regards Anne

Hello Daniel,

thank you very much for your advices. We’ve installed a caching plugin and after the initial load the map loads quick. Perhaps there is a conflict between OUM and our theme Enfold. On another site using theme Total the OUM map loads quickly with more than 1.000 locations and 5 categories without a caching plugin.

Best regards Anne
