Show dropdown arrow always
User
Assistant
The “ element does not show a dropdown arrow by default in most browsers. However, you can use a combination of CSS and JavaScript to force the dropdown to be visible and make it behave like a normal “ element.
### Solution:
1. **Use CSS to add a dropdown arrow manually.**
2. **Use JavaScript to trigger the dropdown on focus.**
#### ✅ **Updated Code**
<style>
/* Force the appearance of a dropdown */
.product_code {
appearance: none;
-webkit-appearance: none;
-moz-appearance: none;
background-image: url('data:image/svg+xml;charset=US-ASCII,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 4 5"><path fill="black" d="M2 0L0 2h4z"/></svg>');
background-repeat: no-repeat;
background-position: right 8px center;
background-size: 10px;
padding-right: 20px; /* Space for arrow */
cursor: pointer;
}
/* Optional: Style the dropdown options */
datalist option {
font-size: 12px;
}
</style>
<input list="product_code-<?php echo $product->get_id(); ?>" class="product_code" name="product_code" value=""
style="font-size: 12px;" data-pid="<?php echo $product->get_id(); ?>"
placeholder="Enter or select the Product Code">
<datalist id="product_code-<?php echo $product->get_id(); ?>">
<?php
if (is_array($p_sku) && count($p_sku) > 0) {
foreach ($p_sku as $data) {
echo "<option value="$data"></option>";
}
}
?>
</datalist>
<script>
document.addEventListener("DOMContentLoaded", function() {
const inputs = document.querySelectorAll(".product_code");
inputs.forEach(input => {
input.addEventListener("focus", function() {
this.setAttribute("list", this.getAttribute("data-pid"));
});
input.addEventListener("click", function() {
this.setAttribute("list", this.getAttribute("data-pid"));
});
});
});
</script>### 🔹 **How It Works**
1. **CSS**:
– Uses `appearance: none;` to remove default styling.
– Adds a manual dropdown arrow using a base64 SVG image as `background-image`.
– Increases `padding-right` to prevent text overlap with the arrow.
2. **JavaScript**:
– Forces the “ to open when the input field is focused or clicked.
– Ensures that the correct `list` attribute is set dynamically.
This will make the datalist behave more like a traditional dropdown. 🚀 Let me know if you need further refinements!
