Hi,
Thanks for letting me know how to hide them, however, I would rather change the placeholder magnifying glass to be a matching icon from my icon set.
Appreciate it
Update: Excuse my lack of CSS knowledge, but I researched and I found that I could override the placeholder with a new background-image using the following code (background-image is a base64 material icon magnifying glass from Google):
input[type="search"].textfilter_::-webkit-search-results-decoration {
