i using below code autocomplete feature in webpage. problem not able navigate through suggestion using mouse pointer. if up/down key pressed once after list item refreshed mouse pointer navigation working fine. could please suggest code change make mouse pointer , keyboard navigation work navigation in html select option? how can improve scrolling of suggestion list using up/down key? html: <div class="field-wrap"> <input type="text" id="college" placeholder="college name" required autocomplete="off"/> <ul id="college_list"></ul> </div> css: .field-wrap ul { width: 93%; margin-top: 1px; border: 1px solid #3498db; position: absolute; z-index: 9; background: #0f0f0f; list-style: none; max-height: 100px; overflow-y:auto; } .field-wrap ul li { padding: 2px; border: solid grey; border-width: 0 0 2px 0; } #college_list { display:

i have following less: ul.dropdown-menu { padding-top: 0; z-index: 2010; li:first-child { a.disabled.heading { &.availableaction { border-top: none; margin: 0; } } } } is there way combine li:first-child , a.disabled.heading , , &.availableaction selectors? do mean this? ul.dropdown-menu { padding-top: 0; z-index: 2010; li:first-child a.disabled.heading.availableaction { border-top: none; margin: 0; } } less supports nesting never requires use it. unasked notes :) hope z-index arbitrary-looking , huge reason if possible, design selector names can .dropdown-menu rather ul.dropdown-menu - browser process first 1 more second if possible, it's practice use less specific selector ul.dropdown-menu li:first-child a.disabled.heading.availableaction . again, browsers process .dropdown li:first-child .availableaction more (and li:first-child .availableaction quicker, can imagine might targe

in recent code writing times i've seen single element contain paddingleft/right, paddingstart/end, , both. can't seem find on better , why. have insight / when use 1 or other or both? you need new start/end properties create nice right-to-left layout, used in countrys people read right left. there no better version, newer version. if want support android versions prior android 4.2, should use old , new properties together. if want support android 4.2 , newer versions, it's ok use new properties paddingstart (instead of paddingleft ). there nice explanation available on android developers blog : to take advantage of rtl layout mirroring, make following changes app: declare in app manifest app supports rtl mirroring. specifically, add android:supportsrtl="true" element in manifest file. change of app's "left/right" layout properties new "start/end" equivalents. if targeting app and

my question given array a, how can give array identical except changing negatives 0 (without changing values in a)? my way is: b = a; b(b<0)=0 is there one-line command , not requiring create copy of a? while particular problem does happen have one-liner solution, e.g. pointed out luis , ian's suggestions, in general if want copy of matrix operation performed on it, way how did it. matlab doesn't allow chained operations or compound expressions, have no choice assign temporary variable in manner. however, if makes feel better, b=a efficient not result in new allocated memory, unless / until b or change later on. in other words, before b(b<0)=0 step, b reference a , takes no memory. how matlab works under hood ensure no memory wasted on simple aliases . ps. there nothing efficient one-liners per se; in fact, should avoid them if lead obscure code. it's better have things defined on multiple lines if makes logic , intent of algorithm
