Multiple chips

Hey guys, I want to include 2 material-chip like this into one page: HTML: <div class="col"> <label><?php _e('Include keywords (Add with ENTER)', 'hypertheme');?></label> <div class="chips filter-result-include chips-placeholder"></div> </div> <div class="col"> <label><?php _e('Exclude keywords (Add with ENTER)', 'hypertheme');?></label> <div class="chips filter-result-exclude chips-placeholder"></div> </div> JAVASCRIPT: $('.chips-placeholder.filter-result-include').material_chip({ placeholder: 'Add', secondaryPlaceholder: '+Tag', }); $('.chips-placeholder.filter-result-exclude').material_chip({ placeholder: 'Add', secondaryPlaceholder: '+Tag', }); Now I add a word into the include chip input. As soon as I type in the same keyword into the exclude material chip input it diapears immediately as soon as I hit enter. But hold on it becomes more odd: If I add a word into the exclude chip input, delete it and want to input the same word again it gets deleted immediately!
