collapse

I have a Data Frame df0 with n columns. Only one of the columns contains a string, all other columns are empty or contain the "" string. Is it possible to collapse the data frame into a single column data frame where for each row I get the non-empty element? df0: A B C 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train should give: 1 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train Maybe: >>> df.max(axis=1) 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train dtype: object which is a Series , not a DataFrame , but you could make one using df.max(axis=1).to_frame(1) or something. If they are empty strings rather than NaN

I want to change the behaviour of the Twitter Bootstrap Menu on small devices to close the expanded menu by either clicking on a menu item or clicking the menu button. Currently (default) I can only collapse it by clicking the menu button in the top right corner, no matter if I'd clicked on a link/menu item or not. How would I do that? I coudln't figure it out from the TB documentation and searching the internet didn't provide any answers. Thanks for the fix Skelly. It worked great on the "mobile" menu, but unfortunately it was causing a visual defect in "desktop" mode as it was targeting .nav

I have a DataGrid with grouped ItemsSource. There are an expander on each group, so I can expand/collapse all the groups. Now, I'm trying to collapse all groups by default, but leave the first group expanded. The items source is dynamic, so I can't build any converter to check the group name. I must do it by group index. Is it possible to do in in XAML? Or in code-behind? Please, help. This might be a little late, but in order to help with similar problems, defining a "Visual tree helper class" would be helpful in this case. // the visual tree helper class public static class VisualTreeHelper

I am trying to find a jQuery solution to show the first 3 items on each menu in a left-hand navigation filter with a 'Show more' and 'Show less' link enabling users to expand the list. I have searched for a solution but most expand/collapse scripts completley hide the layer whilst others show an Expand (Show more) link but do not toggle to show a Collapse (Show less) link. My menus are coded as follows. <div id="menu1"> <ul class="term-list"> <li class="term-item ">Item 1</li> <li class="term-item ">Item 2</li> <li class="term-item ">Item 3</li> <li class="term-item ">Item 4</li> </ul> </div>

I have a form that spans several out-of-the-box Bootstrap Collapse panes. They toggle correctly on a mouse click - now I'd like to implement a way to open a closed pane via whatever event fires when tabbing from the last input of the currently open pane. IOW, as I step thru the input fields of the open pane I can tab from one input to the next - when I tab from the last input the focus goes to the subsequent header region of the next pane. I'd like the act of tabbing to that header region to fire .collapse('toggle') ; I've tried a few variations on: $('#collapseAcct').focus(function () { $('

I am using searchview in my application ( without action bar). How can i collapse searchview after query text submit ? I have these listeners ; @Override public boolean onQueryTextSubmit(String query) { InputMethodManager imm = (InputMethodManager)thisFr.getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(globalSearch.getWindowToken(), 0); return false; } @Override public boolean onQueryTextChange(String newText) { // TODO Auto-generated method stub return false; } I don't use ActionBar so i don't have a function like collapseActionView() . Waiting for help Thanks You

I did a UITableView filled with a plist data source, and I did custom cells with Interface Builder (so I'm using xib files) here's the part of code where I'm creating cells: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; DataTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *views = [[NSBundle mainBundle] loadNibNamed:@"DataTableViewCell" owner:nil options:nil]; for (UIView *view in views) { if ([view isKindOfClass:[UITableViewCell
